Description Jacob Lifshay 2022-11-01 06:41:18 GMT

TODO: determine how much Libre-SOC wants to pay.

Luke and I agree that Libre-SOC should pay for some of the cost of upgrading my PC, since it does benefit Libre-SOC (in fact, being able to run Libre-SOC simulations and stuff much faster is the majority of why I upgraded).

Luke's agreement:

I bought the cpu, motherboard, 64GB of DDR5 ram, and a better heatsink for USD $1355.45

Luke, do you have any suggestions for how much to pay?

Comment 2 Jacob Lifshay 2022-11-04 09:39:28 GMT

All the parts arrived today, I got them installed and ran pytest -n auto in openpower-isa.git, it took 180.80s on 30e18452e6988016e823cd9b9b6fc4b2d4fa1b57

iirc it used to take me around 5m30s (i forgot to check before installing the new parts)

I'll leave this set to IN_PROGRESS while Luke thinks about how much is appropriate for Libre-SOC to pay.

that may be anomalous, i tried benchmarking z3 and it said it took *longer* than it did on my 3900X, so i temporarily installed linux 6.0 (so it has support for temperature monitoring and maybe better cpufreq stuff) and am rerunning it.

so far temperatures don't look like i have thermal issues, it was going to 5.2ghz all-core and to 5.7-8ghz single core.

it's also possible i just have a different version of z3 than i had when i ran it on my 3900x (that was this spring iirc):

It finished rerunning, it took 89m32s vs. 77m36s on the 3900X with a possibly different version of z3.

I'm going to assume the discrepancy is caused by a different version of z3 and not worry about it.

I also reran pytest in openpower-isa, it took 172.97s this time.

Comment 5 Jacob Lifshay 2022-12-01 12:12:35 GMT

i'm thinking maybe 1000 eur would be an appropriate amount...lkcl does that sound good? should I just change the budget fields as needed?
